grinding tests were conducted on an oxidized copper-cobalt ore using a pear-shaped ball mill. twelve mono-sized ore fractions were prepared and wet ground batchwise. the mill was run for 0.5 to min intervals. the shortest interval provided data more closely related to the breakage function because less secondary breakage was hypothesized.
optimization of solids concentration in iron ore ball milling through modeling and simulation. the effect of ball and mill diameters on grinding rate parameters in dry grinding operation. comparison of the bond method for sizing wet tumbling ball mills with a sizemass balance simulation model.
but for agsag mill analyses the standard 14-mesh sieve is typically used. the rod mill work index is computed with an equation very similar to that of the ball mill test, as follows: It is common to observe a difference between the rod mill and ball mill values for a given ore type. these differences may be caused by a variation in ore
milling circuit consists of a rod mill followed by a ball mill in series. crusher product is fed to the rod mill, and the water is fed in ratio to the ore feed mass. the rod mill discharge is pumped, without any further water addition, to the first ball mill. the ball mill discharges to a sump where water is
